This is true that I am trying to accomplish the same task that you have

Hi,
I have implemented the algorithm in the paper for test and uploaded my code

Hi Ben,
Actually, I didn't copy them from another flowgraph.
But, I noticed there is a problem with my PYTHONPATH, which generates this
error. When I correct it, the execution goes well.
Thank you,

Hi Azza -
We have noticed that problem if you have copied UHD source / sinks from
another flowgraph into the one you are using. Try deleting the UHD blocks
and re-creating them in your flowgraph and see if that fixes the problem.
There is some bug in copying those blocks between flowgraphs in GRC

Hi All,
I am using GNU Radio Companion version 3.6.2.
When I execute a simple flowgraph (containing two blocks: USRP Source and
WX GUI FFT Sink), it generates the following error:
*RuntimeError: LookupError: IndexError: multi_usrp: RX channel 214957620880
out of range for configured RX frontends*
Hello GR,
* Is there a way how to run my flowgraph for a given number of
minutes/seconds then stop it.
* I'd like to know too how to reconfigure my flowgraph (after I stop it from
runtime) and resume its run after I changed for example the signal source at
the begin of the flowgraph.
I tried:

Xcode 5.1 is for both OSX 10.8 and 10.9 only, so this "note" applies to both of
those OSX versions.
The new Xcode 5.1 breaks Boost compilation, which in turn breaks UHD and GNU
Radio compilation (in similar ways). Boost upstream already issued a patch to
fix this issue, and it is already incor

Hello,
My application requires very consistent propagation delays from TX to RX
between measurements (within 1 sample or so). I am seeing some odd behavior
and could use a little help.
My flowgraph is as follows:
Vector source -> Frequency mod -> USRP sink
USRP source -> Head -> File sink

Considering the timeline of GSoC, I am more interested in implementing
channel models. That way I can stick to the software domain to test and
validate my work. Also, I have frequently used Rayleigh/Ricean/Nakagami

Hi Azza!
How did you install UHD and GNU Radio, and what is your Device?
Basically, your GNU Radio seems to be built against an UHD version
that is older than the one you have installed.
The best way to solve this issue is usually
1. Making sure to fu
Hi
I want to make block diagram in grc such that the center freq of
usrp_source should be automatically changed in incremental way defined by
min and max boundary. I don't want to take input from qt-qui slider.
Just like the example of usrp_spectum_sense.py but in grc.
How can I do that?
Thanks

Hi All,
After installing UHD and GNU Radio, when I execute any flowgraph using the

Hi Karan,
If you installed this gr-cdma module with DENABLE_DOXYGEN=ON, you can find
the html documentation
Paths were already updated. So that's not the issue I feel.
I will retry using the build-gnuradio script to ensure nothing was wrong
with downloaded tarball.

If you built GNU Radio under pybombs, you can also run
./pybombs rb gnuradio
this alias (rebuild) will blow away the build dir and re-run
cmake/make/install for you with the proper environment set up
don't forget to rebuild everything that links against gnuradio
